1
• Do not disassemble any electrical components of this horn kit (air compressor, air valve, pressure switch).
• Do not attempt repairs or modifications of any component. Please refer to qualified service agencies for all service and repairs.
• Do not operate any component where it can fall or be submerged into water or any kind of liquid.
• Do not reach for any component that has fallen or been submerged into water or any kind of liquid.
• Use the included components with 12 volt DC systems only.
• Do not leave the air system unattended during use.
Safety During Installation
• Disconnect the ground of your battery before beginning your installation.
• Use eye protection when operating drills.
• Take your time and do not rush your installation.
• Never allow children to operate the compressor or air horn. Use close supervision when operating this equipment near children.
• The air compressor will become very HOT during and immediately after operation. Do not touch any part of the compressor with
your bare hands during or immediately after use.
• Do not use this product near open flames, explosive materials or where aerosol products are being used.
• Do not operate this product where oxygen is being administered.
• Do not pump anything other than atmospheric air.
• Never use this product while sleepy or drowsy.
• Do not use any tools or attachments with the supplied air source unit without first determining maximum air pressure for that tool
or attachment.
• Never point any air nozzle or air sprayer toward another person or any part of your body.
• The included compressor is equipped with an automatic reset thermal protector and can automatically restart after the thermal
protector resets. Always cut off power source when thermal protector becomes activated.

PLANNING YOUR INSTALLATION
I. INSTALLING YOUR HORNBLASTERS TRAIN HORNS
RECOMMENDED TOOLS
2
This is the most important step in your installation.
• Plan out the location of each component before starting your installation.
• Make sure you have enough airline and wire to install the system before beginning the installation.
• Make sure mounting locations are secure and void of debris.
• Try to keep the supply wire to the compressor as short as possible. Wires lose voltage over distance therefore shorter wires
will result in better performance.
• Mount your air source unit in a location that is as cool as possible and away from heat sources. This will make your
compressor run cooler and last longer.
• Your air source unit must be mounted upright or on it's side. DO NOT MOUNT UPSIDE-DOWN! Mounting the unit upside-
down will allow any condensation buildup to drain back in to the compressor and harm its components, and also will disrupt
the compressor’s ability to cool properly. *Move the drain cock to the plugged port on the side of the tank if you mount
sideways; plug the drain with the flush-mount hex plug*
• Teflon tape or a locking compound should be used on every fitting in your air system to prevent air leaks; unless a white or
red PTFE paste is already applied.
• Use the supplied 10 gauge wire or thicker (lower gauge #) wire to power your air compressor.
• 1/2” Wrench
• 9/16” Wrench (1/4” NPT Fittings)
• 10mm Wrench or Socket (Air Source Mounting)
•12mm Wrench
•Needlenose Pliers (rubber grommets for tank)
• Drill (7/32” or 6mm Bit)
• Wire Cutter/Stripper
•Included Tubing Cutter
• Eye Protection
Locate an area for your horns that is dry and free from debris. The horns can be mounted in any direction and
still be heard from all around. The horns should not be mounted where they will be completely submerged or
will receive any kind of impact. Horns may be mounted directly to your vehicle, on a medium such as grommet
strips (plumber’s strap), sheet metal or any sort of custom bracket.
1. Locate a secure, dry, and safe position for your horns.
2. Make a mounting template by tracing the mounting bracket on the horn.
3. Using the mounting template drill 7/32” holes for the mounting bracket of the horn.
4. Secure the horn using the supplied mounting hardware.
II. INSTALLING YOUR AIR SOURCE KIT
Locate a flat and secure installation area for the air source unit as well as an area for the air filter that will
remain free of dust, dirt, and debris (your compressors perfor-mance is directly affected by air quality). Try
to keep the distance of the unit from the battery to a minimum to keep your compressor running at
maximum performance.
1. Disconnect the ground cable from the vehicle’s battery.
2. Position the unit in the desired location and secure it using the supplied mounting hardware (10mm).
3. Remove the orange plug in the compressor’s air inlet.
4. Using the supplied hardware, mount the air filter somewhere dry and out of direct contact with moisture.

Air Filter Relocation
Your air compressor came with two barbed fittings and an air filter housing.
Let’s start by taking the fitting on the left with the male thread and inserting it into the compressor
inlet. The other fitting (female end) can be threaded onto the filter housing directly. Your
compressor/filter should look like the image below. At this point, you can use the supplied 3/8” air
line to connect the compressor and filter together.
Route the air filter up to a high and dry location where it will not get wet or exposed to the
elements. The compressor itself is fully sealed but if your filter gets wet, the compressor can pull
water into itself and this will lead to problems later on down the road. Your compressor will last
much longer if the filter is relocated to a high and dry location. Be careful not to kink the air line
while routing the filter around.
*If your compressor is mounted outside where it is exposed to the elements, the filter MUST be
relocated.

III. INSTALLING YOUR AIR TUBING & AIR VALVE
Before cutting any air tubing make sure to double check your measurements. We recommend cutting lengths
with at least an extra inch per line just to be safe. Compression fittings use ferrules (olives) that should be used
only once. When threading any fittings make sure to use Teflon tape to prevent air leaks.
You’re Done!
It’s time to test your horns! Share your install photos on our facebook at www.facebook.com/hornblasters or
instagram/twitter @hornblasters and don’t forget to check www.trainhornforums.com, the largest train horn community
on the internet.
Your train horn kit will use two completely independent circuits. One circuit will connect your horn trigger (push-button
intermittent switch, or toggled factory button) to your electric valve. The other circuit will connect your accessory trigger
(ignition positive wire) to your air source kit.
Fitting Flow Chart [Air Source] » [1/2” Line] » [Air Valve]
1. Plan out the fittings placement out before you begin and make sure you understand the correct order.
2. Make sure that your tank is empty of air and that the compressor is not running during installation.
3. Install the air line carefully using two wrenches for each compression fitting. Use one wrench to hold the
body of the fitting stationary and another to tighten the compression nut.
4. Measure and plumb one length of 1/2” tubing from the tank compression fitting to the air valve located on the horn.
5. Next connect your air valve’s inlet port to your air source unit using 1/2” air line and 1/2” to 1/2”
compression fitting.
Circuit 1
1. Begin by wiring your horn trigger.
a. If you are intending to use your factory horn switch, start by locating the load wire of the horn button
(positive when horn is depressed in a standard vehicle) and wiring it to the included toggle switch.
b. If you are going to use a push button switch (intermittent toggle switch) wire a fused (5A) wire from
any 12 volt source desired (battery) to your switch.
2. Next wire your switch to any pole of your air valve using the female bullet connector.
3. Wire the other side of the air valve to ground using the female bullet connector.
4. Test your circuit by activating your trigger and listening for a ‘click’ from the valve.
Circuit 2
1. Locate an accessory line in your vehicle that is capable of a 16 amp load.
2. Wire your accessory line using an inline fuse (35A) to your air source unit (Red Wire).
3. Ground the other side of your air source unit (Black Wire) to ground.
4. Your air compressor system will not turn on automatically when power is on (Key is in ‘accessory’ or ‘on’
position) and automatically turn itself off upon reaching destination.
IMPORTANT: The air horns and connecting ttings up to the outlet of the air valve will use 1/2” air line. The air
source unit will use 1/2” air line to connect to the inlet port of the air valve.
IMPORTANT: Do not make any kinks in your air line. Doing so will disrupt air ow and the damage is irreversible.
